Abstract: In a particular embodiment, a method includes evaluating, at a mobile device, a first area of pixels to generate a first result. The method further includes evaluating, at the mobile device, a second area of pixels to generate a second result. Based on comparing a threshold with a difference between the first result and the second result, a determination is made that the second area of pixels corresponds to a background portion of a scene or a foreground portion of the scene.

Abstract: A projection display apparatus includes an image generation unit that generates an image light, an optical system that projects the image light onto a projection plane, an optical path changing unit that changes a display position of the image light on the projection plane, and a controller. The controller generates signals for plural types of sub-frames by dividing spatially a signal for each frame of the video input signal. The controller controls the optical path changing unit to keep the display position of the image light on the projection plane before and after transition of the frame of the video signal, and controls the image generation unit to make a type of a beginning sub-frame in a frame output just after the transition equal to a type of a last sub-frame in a frame output just before the transition.

Abstract: In a digital contents receiver for receiving transmitted digital contents, the digital contents include at least component information indicating an element which constitutes a program of the contents. When the component information indicates that the received digital contents are a 3D component, it is determined whether a display part corresponds to display of the 3D component. If the display part corresponds to display of the 3D component, the received digital contents are displayed in 3D.

Abstract: A system for estimating daytime visibility conditions includes a camera configured to capture a video sequence over a period time, an odometry sensor configured to monitor motion of the camera, and a video processing unit in communication with the camera and with the odometry sensor. The video processing unit is configured to receive the video sequence from the camera, detect an object within the video sequence, estimate a distance between the camera and the object for each frame of the video sequence, determine a mean perceived brightness of the object for each image frame, and estimate an ambient visibility using the estimated distance and mean perceived brightness of the object.

Abstract: A video encoder may include a context-adaptive binary arithmetic coding (CABAC) encode component that converts each syntax element of a representation of a block of pixels to binary code, serializes it, and codes it mathematically with its probability model, after which the resulting bit stream is output. When the probability of a bin being coded with one of two possible symbols is one-half, the bin may be coded using bypass bin coding mode rather than a more compute-intensive regular bin coding mode. The CABAC encoder may code multiple consecutive bypass bins in a series of cascaded processing units during a single processing cycle (e.g., a regular bin coding cycle). Intermediate outputs of each processing unit may be coupled to inputs of the next processing unit. A resolver unit may accept intermediate outputs of the processing units and generate final output bits for the bypass bins.

Abstract: An object observable in various images of an environment is recognized as being the same object, even when partially occluded in some images. In one particular implementation, the object is a hand which may be used for gesture input to an augmented reality system. A flexible similarity measurement metric is computed to aid in determining whether hands captured through 2D images of the environment are the same or different, regardless of whether the hands are fully observed or partially occluded. The similarity measurement metric accommodates for translation, rotation, and scaling of the hand to enable recognition of a common hand through a sequence of images even if that hand is partially occluded in some images.

The method also includes storing the reference image in a memory associated with the device.

Abstract: A user activation of an image capture function of a mobile device is received. The image capture function is for a surround image mode. Two or more camera lenses are approximately concurrently activated. A front-side image from a first camera lense and a rear-side image from a second camera lense can be optically captured.

Abstract: A system for capturing live-action three-dimensional video is disclosed. The system includes pairs of stereo cameras and a LIDAR for generating stereo images and three-dimensional LIDAR data from which three-dimensional data may be derived. A depth-from-stereo algorithm may be used to generate the three-dimensional camera data for the three-dimensional space from the stereo images and may be combined with the three-dimensional LIDAR data taking precedence over the three-dimensional camera data to thereby generate three-dimensional data corresponding to the three-dimensional space.

Abstract: A method of encoding a motion vector includes: selecting one of a plurality of predicted candidate motion vector sets by using motion information of neighboring blocks of a current block; selecting one of predicted candidate motion vectors within a selected predicted candidate motion vector set, as a predicted motion vector; encoding a differential motion vector representing a difference between a current motion vector or motion vector of the current block and a selected predicted motion vector; and encoding a predicted motion vector index indicating the selected predicted motion vector. As a motion vector is encoded after selecting an efficient predicted candidate motion vector set, the size of a differential vector to be encoded can be reduced without necessarily encoding additional information to indicate which set of predicted candidate motion vectors has been selected, resulting in improved compression efficiency of motion vectors and in turn the improved video compression efficiency.

The computer program code may further cause the apparatus to determine one or more focus points of interest in the media content indicating areas or locations of interest that are associated with the event. The computer program code may further cause the apparatus to classify the focus points of interest based in part on analyzing respective items of the sensor data. Corresponding methods and computer program products are also provided.

Abstract: A video encoder may include a context-adaptive binary arithmetic coding (CABAC) encode component that converts each syntax element of a representation of a block of pixels to binary code, serializes it, and codes it mathematically, after which the resulting bit stream is output. A lookup table in memory and a context cache may store probability values for supported contexts, which may be retrieved from the table or cache for use in coding syntax elements. Depending on the results of a syntax element coding, the probability value for its context may be modified (e.g., increased or decreased) in the cache and, subsequently, in the table. After coding multiple syntax elements, and based on observed access patterns for probability values, a mapping or indexing for the cache or the table may be modified to improve cache performance (e.g., to reduce cache misses or access data for related contexts using fewer accesses).
